The invention relates to a fluorescent screening system including a white light source exciter, a first light filter piece set, a second light filter piece set, a CCD camera and a lens. The white light source exciter emits a white light source which is then transported to the first light filter piece set. Both the first light filter piece set and the second light filter piece set respectively includes a plurality of different band-pass light filter pieces. Each band-pass light filter piece allows the light source signals in corresponding wavebands to pass while light source signals in other wavebands are filtered away. Under control of a light filter wheel, the first light filter piece set selects one light filter piece according to screening demand of fluorescent proteins in different wavelengths. The white light source, when being filtered through the light filter piece, selects excited light in required wavelength. The selected excited light then is transported to a sample to excite a fluorescent signal. The second light filter piece set selects one light filter piece under control of the light filter wheel, so that the fluorescent signal can pass through the light filter piece in the second light filter piece set to remove stray light signals. The fluorescent signal finally is collected by means of the lens to complete fluorescent imaging with the CCD camera.
